OVERIELOW-SIGNAL.

Application filed .1 uly 21, 1915.

To all whom it may concern Be it known that I, lVILLIAM J ABERLE, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Overflow-Signals, of which the following is a specification.

My invention relates to improvements in alarms for sounding a warning when receptacles are about to overflow, or when liquid which is being delivered into the receptacle as for example, through a faucet, has reached the desired level.

More particularly this invention is adapted to be readily attached to or detached from bath tubs, sinks and the like and is simple and inexpensive in construction and effective in operation.

The parts of my invention are susceptible of adjustment whereby the alarm may be made to operate when liquid which is fed into the receptacle has reached any predetermined level.

The device is also so constructed as to fold into compact form for storing or transporting.

With these and other objects in view my invention comprises the features of construction and combination of parts hereinafter more particularly described and claimed.

In the drawing forming part of this specification, Figure 1 is a view partly in elevation and partly in section; Fig. 2 is a perspective of the supporting member, and Fig. 3 is a view partly in elevation and partly in sectionof a detail.

In the drawing A indicates a receptacle of any suitable design and configuration and to which my invention is removably attached to sound an alarm automatically when liquid delivered thereunto reaches any predetermined depth.

B is a support comprising, a vertical alarm holding arm 2 having a longitudinal slot 3, said holder terminating at its base in a horizontal support 4: and a horizontal float guide 5, said horizontal support and guide, as shown, extending in opposite directions from the vertical arm 2, though, of course any other preferred arrangement of the parts to meet varying conditions may be effected. The support at is shown provided with a clamp 6 secured by a clamp bolt 7 and cooperating with the support to engage Specification of Letters Patent.

Serial No. 41,091.

the rim 8 of the receptacle and secure the device rigidly thereon with the guide overhanging the edge of the receptacle and projecting inwardly therefrom.

Mounted upon the support 4t and slidable up and down therein is a carriage 9 having an integral pin 10 working within the slot 3 and a stud bolt 11 projecting from a boss 12, in the inner side of the carriage, freely through said slot and secured by a thumb nut 13 on the stud bolt to said support in any selected vertical position. The carriage 9 carries a spring alarm bell C of any suitable ordinary construction having a spring pressed downwardly extending release pin 14, which when depressed releases the alarm sounding mechanism within the bell in the usual manner. Hinged upon the lower end of the carriage by the pintle 15 is a trigger arm 16 which is positioned with its portion adjacent said pintle so as to press against said release pin 14 when the lever is swung or forced upwardly by its free end. Normally the lever arm is held horizontally in juxtaposition to the pin 14 by aleaf spring 17 secured to the carriage and releasingly pressing against the journal portion of the lever in a notch 18. This notch is of sufioient width so as not to impede the upward swinging movement of the lever but on the other hand prevents the lever from accidentally dropping or swinging downward out of normal position. However the lever can be thrown down from normal into substantially vertical position when desired for purposes to be hereinafter described.

Slidably mounted through a vertical guide sleeve 19 carried by the guide 5 is a stem 20 secured at its lower end to a float 21, said stem having a stop screw 22 on its upper end which holds the stem against removal from the guide except when desired' The height at which the alarm is adjusted on the support B determines the depth of the liquid in the receptacle, when the alarm is automatically sounded. As the water level rises within the receptacle, the float causes the stem to move upwardly through the sleeve 19 against the free end of the trigger 16, which, in turn actuates the sounding mechanism to give the alarm.

When desired, the trigger may be swung down with its free end out of the path of movement of the stem so as not to sound the alarm, and the device may be entirely removed and arranged into compact form, so as to occupy a minimum amount of space.

In accordance with the patent statutes, I have described the principles of operation of my invention, together with the apparatus which I now consider to represent the best embodiment thereof, but I desire to have it understood that the construction shown is only illustrative, and that the invention can be carried out by other means and applied to uses other than those above set forth within the scope of the following claim.

Having described my invention, What I claim as new and desire to protect by Let ters Patent is:

An overflow alarm, comprising a support having means for fastening it to a receptacle, a stem carrying a float vertically reoiprocable with respect to said support, an alarm carried by said support, and a trigger adapted to be thrown from inoperative position without to operative position within the path of travel of said stem and to be actuated thereby to sound said alarm.

In testimony whereof, I have signed my name to this specification.

WILLIAM J. ABERLE.
